I am Atari 800XE user since 1985 when I was 5.
It was my first computer. So it is my fav platform so far...
Now I have 5x Atari 130XE. One with stereo Pokey upgrade and 1MB ram.
And I also have SDrive interface (SD card as FDD).
What Atari setup do you have?

The 6502 emulator is just a separate project, but in the future I want to port more of my emulator, which was written in C and fairly complete. Except sound, which is hard to get right.

I had an 800XL, eventually with a 1 MB MegaRAM. My collection was much bigger, but I only have a few pieces left. We even bought a considerable part of the inventory of Atari Europe when they withdrew from the continent. I still have a new 800XL in box for my retirement.
